Bushing Types

There are several types of transformer bushings, each designed for a specific purpose and application. Some of the most common types of transformer bushings include: Oil-impregnated paper bushings: These are the most common type of bushings, particularly in small and medium-sized transformers. They consist of a paper insulation impregnated with oil, which provides both electrical and mechanical insulation. Resin-impregnated paper bushings: These bushings are similar to oil-impregnated paper bushings, but use resin instead of oil as the impregnating agent. Resin-impregnated paper bushings are more environmentally friendly, as they do not contain oil. Epoxy resin bushings: These bushings are designed for high-voltage applications and have a higher mechanical and thermal strength than paper bushings. Epoxy resin bushings are also more resistant to environmental stresses and are less prone to moisture ingress. Composite bushings: These bushings use a combination of materials, such as s...
